Miniaturization is a key technological approach to realize high performance separation systems that have several important features required in modern analytical methods. A smaller scale of the stationary phase synthesis enables a systematic analysis of the retention behavior and also a more efficient development of novel stationary phases in liquid chromatography. Development of microscale sample preparation technique has been regarded as a valuable supporting approach to the development of microscale separation methods. Effective on-line coupling of the microscale sample preparation and separation allows an efficient and rapid analysis without a loss of sensitivity for most of the analytical separations. In this review, development of the miniaturized separation techniques and the applications have been described from the view point of the authors' research group, including the development of novel stationary phase, microscale sample preparation techniques for liquid and gas sample matrices.

“…A few LCP have already been used in SFC, but with glass [56 60] or packed [61,62] capillary columns. On packed steel columns planarity recognition is increased, as previously reported by Pesek and Williamsen [63], whereas length-to-breadth solute recognition is no more rigorously observed than in RP HPLC.…”

Key WardsColumn liquid chromatography Review of liquid-crystal stationary phases Bonded stationary phases Coated liquid-crystal polymers Molecular-shape recognition SummaryThe use of liquid crystals as stationary phases for liquid chromatography is reviewed. The synthetic pathways used for covalent immobilization of low-molecular-weight liquid crystals on the silica-gel surface are discussed. The techniques used to characterize stationary phase structure are also presented. Finally, the trend for replacement of low-molecular-weight liquid crystals by liquid-crystalline polymers, either coated or bonded, is described. Examples are given of the separation of specific chemical compounds on liquid-crystalline stationary phases.liquid crystal on the solid support. The three-dimensional liquid crystal system in GC thus becomes a two dimensional system in HPLC.We will describe first the different synthetic pathways used to bond low-molecular-weight (LMW) liquid-crystalline molecules to silica gel particles, and the physicochemical characterization and chromatographic properties of these liquidcrystal-based stationary phases for HPLC.The alternative use of liquid-crystalline polymers (LCP), either coated or bonded to silica, will also be presented and trends in the use of liquid crystals as stationary phases in HPLC will be introduced.
